Application led July 26, 1910. Serial No. 574,007.

To all whom it may concern:

Be it known that I, CHARLES A.. CONDE,

; a citizen of the United States, residing in Camden, New Jersey, have invented certain Improvements in Sheet-Metal ShaftIIanger's, of which the following is a specification.

My invention consists of certain improvements in the sheet metal shaft hanger' constituting the subject of my Letters kPatent No. 966,527, dated August 9, 1910, the object of my present invention being to simplify, strengthen and cheapen the construction of the various parts of the hanger, all as hereinafter fully set forth.

In the accompanying drawingswFigure 1 is a vertical longitudinal section of my improved hanger showing the shaft box in position therein; Fig. 2 is a vertical transverse section on the line a-a, Fig. l; Fig. 3 is a vertical transverse section on the line -b, Fig. 1; Fig. 4: is a vertical transverse section on the line c-c, Fig, 1; Fig. 5 is a horizontal section on the line af-cl, Fig. 1; Fig. 6 is a horizontal section on the line. e-e, Fig. l; Fig. 7 is a horizontal section on the line f-f, Fig. 1; Fig. 8 is a horizontal section on the line g-g, Fig. 1; Fig. 9 is a horizontal section on the line laf-J1., Fig. 1; Fig. 10 is a horizontal section on the line z', Fig. 1; Fig. 11 is a horizontal section on, the line j-y', Fig. 1; Fig. 12 is a vertical transverse section on the line c-c, Fig. 1; Fig. 18 is a longitudinal vertical section of a modified construction of hanger leg and yoke, and Figs. 14 and 15 are transverse vertical sections, illustrating difi'erent forms of side webs of leg and yoke, used in such construction.

The hanger resembles that of my former application in that it consists of opposite de pending side legs, feet at'the upper ends `of said legs, connected or not by a cross as before, of a hollow box-like girder 1 hav? ing a back web, side webs and inner flanges, the latter being parallel with the back web in the upper portion of the leg but said Speccation of Letters Patent.

Patented Mar. 9, 1915.

flanges being Vgradually bent as they approach the intermediate cross brace, as shown in Figs. 6, 7, and 8, until they assume a position at right angles to the back web, as shown in Fig. 9, for the attachment of the side webs of the said intermediate brace to which they are secured by means of transverse rivets or bolts, as shown in Fig. 9, the inner edges of the flanges being then bent toward each other again, as shown in Fig. 10, at a point between the intermediate brace and the bottom yoke, and being again straightened as shown in Fig. 11, so as to be parallel with or bear against the side webs of said yoke, as shown in Figs. 11, 12 and 13, the outer web of each leg having a central, inwardly projecting rib 2 formed upon it inV order to increase the rigidity of the leg, as shownV in Figs. 6, 7 and 8. The foot member at the upper end of each leg consists of a cup-like outer portion 3 and an inner downwardly projecting socket 4 which receives the upper end of the leg and conforms in shape thereto, as shown in Fig. 5. The contacting webs of the leg and socket are flared from bottom to top, as shown in Figs. 1 and 3, and are secured together by rivets or bolts 5, as shown in Figs. 1 and 3, and said foot member is closed at the top by a cap plate 6 which is secured in place by ortimpingtheupper portion of the foot mem` ber 2 inwardly over the downturned edges of the cap plate, as shown at 7 in Fig. 1. 'Ihe outer web of the socket 4 follows the contour of the rib 2 and is secured to the outer web of the leg by means of a bolt or rivet 9, as shown in Fig. 5.

In order to stiffen and strengthen the cupshaped portion of the foot member, the latter is provided with a transverse channel bar 11 interposed between the base of said' cup-shaped portion and the cap plate 6, and to further stien this portion of the foot member, longitudinal angle bars 12 are disposed between the base of the channel 11 and the cap plate 6 on each side of theopening in the foot member intended for the recep` tion of theA bolt or bolts whereby the hanger isfsecured to the joist or other support therefor, the bases of the channels 11 and 12 being secured to the base of the cup-shaped portion 3 of the foot member by means of bolts or rivets 13, as shown in Fig. 4.'

In hangers ofsmall size the'footVmem-f bers 2 may be/disconnected from one another but in hangers of a larger size I connect them by means of atop brace of channel form, this brace having, at-eachend, a'iiar- Ying web 16a Ywhich'is secured to `the Haring inner web of the socket 4 by the same bolts or rivets 5 which secure the inner iianges of the leg member thereto. n

. The intermediate cross brace is of H- shaped cross section, as before, and is preferablycomposed of two channel bars 16 and 17 disposed back to .back -and having their meetingy webs suitably bolted ,or riveted to oneanother, but in the present hanger the side Webs of .each of these channel ba-rs are turned inward toward each 4other so as .to

formuflanges 17a, `those of .thelower channel bar providinga support for :the nut 19V which receives the upper adjustingscrew 20 for the :shaft box, and those ofthe' upper channel vbar supporting the -lock nut 2l, or a washer y22, which Yis interposedv kbetween said flanges and the lock nut. Ashort channel lbar 23 Ais interposed .between the nut 1.9 and .the :base web of the lower channel bar 17, :as shown fin Fig. :2, so as to vertically conne the nut 19'.

of fthe corresponding leg 1 and through a..k like opening ina reinforcing plate 25 bolted Each -of the side adjusting vscrews '24 kfor the shaft boX passes, as before, through an opening fin a vertical offset of the back -web or riveted to the inner face of said-web, the

bolt being adapted to a nut 26 which is pre-y vented from turning -by :contact `with the' the legs, as Vshown in Fig. 12, and being se-A cured thereto by bolts 29, the vhead 30 of each'bolt bearing upon a washer which rests upon .an inturned flange 32 of the back web of the reinforcing plate 25, this yflange overlapping inturned flanges 33 at the lower ends of the side webs of said reinforcing plate, as shown in Fig. 12. Turning of the bolt head 30 is prevented by contact of the same with the side webs of the reinforcing Y plateand vertical displacementfofthe :bolt is prevented by means of a retainer plate 34,V

which is secured in place vby meansaof abolt or rivet 35 passing throughit and also Vthrough the back webs of the reinforcing plate and leg, as shown in Fig. 1. A nut 36 is applied .to the lower end of the bolt 29 and bears against the bottom web Vof the 1 yoke .27'.01 against a washer interposed be-y tween 1said web :and the nut, or, if desired, a

" rivet may replace .the bolt and nut yas a means ofsecuring the yoke to the lower ends Yof the legs. In order to aid kin resisting lateral strain which might otherwise be exerted upon Vthe bolts or rivets whereby the yoke is secured to the legsofthe hanger, the botn supported upon achannel bar 42 in theyoke,

turning ofsaid nut being prevented by bending inthe side lwebs of the yoke,as shown in Fig. 2 so as to bring them linto close relation to or'contact with the :sides `of the nut. A lock nut 43 for the.V lower adjusting screw 40 bears upon the .bottom web of :the yoke or upon .a washer interposed between the said web .and the nut. f

In Vthe present hanger .the connections be-v tween the upper ends of the legs and the footl member `3 is more substantial -than in the hanger constituting the subject Yof my previous application, the .construction of the intermedia-te cross brace is simplified, the number o-f parts composing .the same is reduced, and the yoke connection ,at VVthe bot` tom of the hanger is strongand rigid.

The side webs of the bottomyoke may, if desired, be located on .the outsidev ofthe side' webs of ythe legs, as shown in Fig. 13, and the fianges 39 may be located outside :of ythe back webs of the reinforcing plates. Inconstructing the hanger shown in Fig. 1 :thesidev webs of thevlegs and yoke may be beveled,

Y as shown in' Fig. 14, to .resist upward .pressure, or said side webs of l:the 'legs may :be offset to form'shoulders 'for vbearing against the side webs of the legs, as shownin'Fig. 15

for the same purpose. i

. The terms upper and lower as used herein are notto be taken as indicating that the hanger is necessarily :to be used as a depending hanger, as it is evident that it can be reversed and mounted upon a floor or other support so as .to constitute afshaft supporting pedestal. l

I claim:

1. In a sheetmetal-shaft hanger, .thefcom- 1 bination of a hollow, girder-shaped leg, a foot ymember having asocket vthereon forthe reception of said leg, and a :cupslike portionk extending outwardly fromsaid socket.

" 2. Ina sheet metal shaft hanger, the comi Vwith an internal transverse channel said foot member having a cup-shaped portion with an internal transverse channel bar, and a pair of longitudinal angle bars spaced apart within said transverse channel bar.

4. A sheet metal shaft hanger having girder-shaped side legs, a yoke for connect# ing the bottom portions of they legs, a reinforcing plate on each leg, having anges at the bottom, and bolts passing rkthrough the bottom web of the yoke and through the flanges of the reinforcing plate.

5. A sheet metal shaft hanger having girder-shaped side legs, a yoke connecting the lower portions of said legs, reinforcing plates having inturned flanges both on its back web and on its side webs, and bolts passing through said flanges andy through the bottom web of the yoke.

6. A sheet metal shaft hanger having girder-shaped side legs, and a yoke connecting the lower ends of said side legs and having side webs disposed inside of the side webs of the legs, the latter being offsetso as to resist upward thrust upon the yoke. e n

7. A sheet metal shaft hanger having gir-y side webs disposed inside of the side webs of .the legs, the side webs both of the legs and yoke being offset to resist upward thrust upon the yoke. i 8. A sheet metal shaft hanger having girder-shapedside legs, reinforcing plateson the inside of the same, and a bottom yoke having upturned end flanges confined between the back webs of the legs and the reinforcing plates.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
